Phorodon cannabis
Cannabis Aphid, Hemp Aphid
Phorodon cannabis is a monophagous aphid pest specialized on hemp (Cannabis sativa), causing significant damage in field and greenhouse cultivations. Native to Eurasia and North Africa, it was first detected in North America in 2016 and has since spread to multiple U.S. states and Canada. The species feeds on phloem sap, causing plant wilting, yellowing, and yield reduction, and transmits Cannabis Streak Virus. Optimal development occurs at 25°C, with mild abiotic stress paradoxically stimulating reproduction via hormesis.
